HEEL-BREASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 434,333, dated August12, 1390.

Application filed November 14, 1889. Serial No. 330,254. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM GORDON, of Boston, in the county of Suifolkand State of Massachusetts, have invented certain new and usefulImprovements in Heel-Breast-ing Machines, of which the following is aspecification.

This invention relates to that class of machines for breasting ortrimming ofi the front edge or breast of boot and shoe heels in whichthe boot or shoe having the heelto be breasted is pressed against thebreasting-knife, the latter being supported against the pressure exertedupon it by the heel, the boot or shoe being placed upon a jack under theknife and raised by any suitable system of foot or other power andbrought into contact with the edge of said knife, and forced upwardly toperform the cutting or breasting operation. Heretofore in machines ofthis class the breasting-knife has been rigidly held so that it couldnot move in any direction, so that the cutting has to be performed bythe direct pressure of the leather against the knife, an operation whichrequires the exercise of a considerable degree of force and causes rapidwear of the cutting-edge of the knife.

My invention has for its object to provide a machine of this class withmeans whereby the knife may be given a reciprocating movement during thecutting action, thereby securing a double cutting action, the heel beingpressed against the knife in the usual manner and receiving also thecutting action due to the reciprocating motion of the knife.

To these ends the invention consists in the improvements which I willnow proceed to describe.

Ofthe accompanying drawings, forming a part of this specification,Figure 1 represents a side view of my improved machine. Fig. 2represents a front View of the same. represents an enlarged top View ofthe knifeoperating devices. Fig. at represents a section on line 1 1,Fig. 1.- Fig. 5 represents a section on line 3 3, Fig. 3. Fig. 6represents a section on line 3' 3, Fig. 3. Fig. 7 represents a sectionon line to m, Fig. 3; Fig. 8 represents a section on line 5 5, Fig. 3.Fig. 9 represents a section on line 6 6, Fig. 6 5 and Fig. 10 representsa rear view of a portion of the machine.

The same letters and numerals of reference indicate the same parts inall of the figures. In carrying out my invention I provide a standard a,having on its upper end bear-- g represents the breasting-knife carrier,

which is here shown as a bell-crank lever pivoted at it between two armsc'j formed 011 or attached to the standard a. v Said carrier is providedat its inner end with a socket k, which is bored out to receive abushing or bearing Z for the eccentric wrist or crank f, the arrangementbeing such that when the shaft d, on which said wrist is formed, isrotated the carrier 9 willbe rocked on the pivotpin it, as will beclearly understood by reference to Figs. 3 and 4.. The bushing Z ismoved vertically in the end of the carrier as the shaft d rotates, andat the same time permits free lateral movement of the arm, space beingprovided between the end of the wrist and the end of the bore in thebushing to compensate for the oscillating motion. of th carrier g duringthe operation.

- The above-described arrangement of the connection between the crankfand carrier 9 is clearly shown in Figs. 3, 4, 5, and 7. The bushing 1consists of two parts or sections, so that the wear of the bushing maybe taken up by the bolt m, which passes through one arm of the carrierg, said arm and the socket 70 being split, as shown at n, so that thesocket may be compressed by the bolt m.

0 represents the breasting-knife, whichis attached to the carrier g, andis preferably curved in cross-section at its cutting portion, as shownin Fig. 8, the radius of the curve being the center of pivot h. Theknife is directly secured to a head 19 on the carrier g, said headhaving a dovetail groove formed in its outer face to receive thedovetail edges of the knife. The knife is secured to the head by bolts19 b and is vertically slotted to. receivesaid bolts and permit verticaladjustment. The rear side of the knife-holding head is provided withashank q, arranged to enter a socket in the carrier g and fit closelytherein. Said shank is provided with a feather or projection 1", whichenters a slot 8 in the carrier g, the object being to prevent the shankg from turning in the socket and at the same time permit longitudinaladjustment of the shank in the socket, the latter being split andprovided with two ears ta, through which passes a bolt 1), so that whenthe shank is in the proper position in said arm it maybe tightly grippedand held firmly in place.

In Figs. 1 and 2 I have shown the means for supporting the boot or shoeand pressing the heel thereon against the knife. Said means consist of ajack 2, pivoted at its lower end to a rod 3, to the lower end of whichis pivoted a link 4, which link is connected with alever 5, fulcrumed onan arm 6, secured to the support a. Said leveris connected atits otherend to a link 7, which connects with a treadlelever 8, the outer end ofwhich is secured to cars 9, formed 011 the base of the support a. Theabovenamed devices are guided by brackets 10 11, attached to thestandard a, said brackets having guides in which the rod 3 is fitted toslide.

The jack 2 is adapted to swing out, as shown in dotted lines in Fig. 2,so that the operator may more conveniently apply or remove the shoe fromthe last a, the shank b of which is pivoted at c, and has a limitedmovement thereon, so that the last may be tipped forward or back, as thecase may be, to give the breast of the heel an angular cut; or, in otherwords, to incline the breast back- Wardly from the top lift, as issometimes the practice.

d represents a guide to steady the jack 2 and also to serve as a stop toguide the operator in the breasting operation, the jack 2 bringing upagainst the inner end of said guides when the heel 8 is in position forbrcasting. A spiral spring 6, surrounding the rod 3 and resting on thearm 10 and bearing against a collar f on said rod, supports the jack andlifting devices in the position shown in Figs. 1 and 2, and alsoprovides against a jar or shock when the jack is lowered.

9 represents an adjustable gage or stop, by which the cutting of thesole is prevented. Said stop is secured adjustably to a soeketed boss h,formed on thehead p, and is arranged to come in contact with the sole ofthe shoe at the moment that the knife has finished breasting the heel.It will be seen by reference to Figs. 3, 4, and 5 that the rapidrotation of shaft (Z imparts a lateral vibrating or reciprocatingmovement to the arm g through the crank or wrist f. The knife is thusoscillated or reciprocated lengthwise while itis breasting the heel, sothat it cuts with a drawing motion, which greatly increases the ease ofthe operation and reduces the power expended by the operator to theminimum.

I do not limit myself to the details of mechanism here shown, as thesame may be vari ously modified and any other suitable means adopted foroscillating or reciprocating the knife longitudinally without departingfrom the nature or spirit of the invention. If desired, the knife may begiven a rectilinear instead of an oscillating reciprocating movement, inwhich case the cutting-edge would be straight insteadof curved.

I claim- 1. In a heel-breasting machine, the combination of abreasting-knife, a jack orlast-support, means for moving said jacktoward and from the knife, a holder or carrier supporting thebreasting-knife and movable crosswise of the bottom of a boot or shoesupported by said jack, means for supporting the knifecarrier and knifeagainst the pressure of the heel upon its edge caused by the movement ofthe jack toward the knife, and mechanism for giving the carrier andknife a lengthwise movement across the bottom of the boot or shoe,whereby the knife is given a drawing action while cutting the heelpressed against it by the movement of the jack, as set forth.

2. In a heel-breasting machine, the combination of the pivoted carrier,the breastingknife attached thereto and having a curved cutting-edge,means for oscillating the carrier and thereby reciprocating the knife ina curved path, a jack or work-support, and means for moving it towardthe knife in adirection substantially at right angles with the path ofmovement of the knife, as set forth.

3. In a heel-breasting machine, the combination of the bell-crank leveror knife-carrier pivoted to a fixed support, the breasting-knife securedto one arm of said carrier, the driving-shaft having an eccentricwrist-pin engaged with the other arm of said carrier, whereby the latteris oscillated and the breasting-knife reciprocated, and a jack orworksupport and means for moving the same toward the breasting-knife, asset forth.

at. The combination of the bell-crank lever or knife-carrier pivoted toa fixed support, means for oscillating said carrier, the head 19, havinga shank (1 adjustable in a socket in the carrier, means for securing theshank q at any point to which it may be adjusted, a breasting-knifesecured to the head 1), and a jack movable toward and from said knife,as set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 4th day of November, A. D.1889.

WILLIAM GORDON.
